TIRE-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 253,935, dated February21, 18 82.

Application filed October 6, 1881.

To all whom it may concern Be it known that I, JOHN T. MGENNANEY, ofAtlanta, in the county of Fulton and State of Georgia, have invented anew and useful Improvement in Spoke and Tire Tighteners,which'improvement is fully set forth in the following specification andaccompanying drawings, in which- Figure l is a perspective elevation ofth spoke and tire tightener attached to the section of a wheel, and Fig.2 is a top view of the clamp.

The object of my invention is to provide a spoke and tire tightener, andit belongs to that class in which the felly is expanded and theindividual spokes are forced into the hub, as will be hereinafter morefully shown.

In the accompanying drawings, Areprcsents the felly, and B the spoke.Encircling the spoke is a clamp formed of two, semicircular parts, 0 C.These are hinged together at one end at D, and at the opposite end thepart 0 is provided with a threaded bolt, E, carrying a nut. This bolt ishinged atF to the part 0, and when desired for clamping purposes the nuton the end of this belt is swung into position and screwed up againstthe projectingend of the part 0. The ends of the circular clamp O areeach provided in their upper face with sockets G,in which are-looselyplaced the lower ends of the legs I, that project from the cross frameH, resting on the felly.

J represents across-bar, through which centrally passes thescrew-threaded bolt N, having a nut, O, at its upper end. Thelower endof this bolt rests in a socket in the cross-frame H. At each end of thecross-bar Jis an arm, K,havin g a hook,M, at the lower end, on which thefolly A rests. The upper end of this arm (N0 model.)

is screw-threaded, L, and passes through a screw-threaded aperturein theend of the crossbar.

The operation of the device is as follows: The bolt N is detachable fromthe cross-frame H, and the legs I are also removable from the clampbelow. Fig. 1 represents the device as it has been placed on the wheel,the clamps O G being loose on the spoke. To adjust it for operation thescrew N is turned up to the po- 'sition indicated by the dotted lines,and the cross-frame H carrying the legs I, and also the clamps G O,raised to the position shown by the dotted lines, when the nut on bolt Eis tightened, causing the clamps O G to bind on the spoke. Thus thecross-frame H is elevated above the felly and the hooks M rest againstthe under side of the telly. The boltN is now screwed downward by meansof a wrench on the head 0, thus forcing the spoke downward andsimultaneously raising the felly, when a washer is placed between theend of the spoke and the felly to compensate for the wear of the wheel.

Having described my invention I claim In a spoke and tire tightener, theadjustable clamp O O,in the upper side of which are loosely socketed thelegs I I, projecting downward from the frame H over thefelly, incombination with the threaded bolt N, passingcentrally through across-bar, J, and socketed in the cross-frame H, and carrying at eachend a screw-threaded arm, K, having at the lower end a hook, M, to beplaced under the felly, substantially as and for the purpose herein setforth.
